I don't mind adding a heads up for future frameworks but perhaps it is better
to address the Trolltech work in 1.2 once it is working.
These guidelines and our accessibility review and modifications to ODF 1.1,
are first and foremost about interoperability. Accessibility reviews don't usually
got to that level of detail which is why the first W3C web content accessibility guidelines
have holes as does HTML with respect to accessibility. That is why I introduced
ARIA (formerly DHTML Accessibility) to the W3C and it is also the motivation for many
of the changes for W3C Web Content Accessibility Guidelines 2.0.
Developers need to know how to support a solution that is interoperable with
assistive technologies. If ATs don't support what you are providing the developers
get frustrated and often walk. The Qt accessibility people have done an outstanding
job moving that framework forward but it is just not supported by ATs yet.
These guidelines were to direct office developers toward a solution which will
work with ATs. I agree with Peter that I hope by ODF 1.2 Trolltech will be there
and we can include them in the list of supporting frameworks.
The point about saying that IAccessible2 was donated by IBM was merely to point out
that large companies feel accessibility is important enought to go the extra mile
and get it out there. It is also a statement that "out there" should mean "open and free
to use by all." 5 years from now nobody will remember that IBM ever donated it. Hopefully,
we will have moved on, to address new issues, and won't be milking the same old press releases. :-)
If there is a concern about mentioning IBM here we can remove it. I would like
to mention IAccessible2 as it does deal with interoperability.
